◆ ComplexSizeChangedSignal() [3/3]

ComplexSizeChangedSignal::ComplexSizeChangedSignal	(	const QRect &	portionOfOldImage,
		const QSize &	transformedIntoImageOfSize )

A helper method calculating the still points from image areas we process. It works as if the source image was "cropped" by portionOfOldImage, and this portion formed the new image of size transformedIntoImageOfSize.

Note, that portionOfTheImage may be equal to the image bounds().

Definition at line 23 of file KisImageSignals.cpp.

{
    oldStillPoint = QRectF(portionOfOldImage).center();
    newStillPoint = QRectF(QPointF(), QSizeF(transformedIntoImageOfSize)).center();
}
